Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a non-standard hot air circulating oven air duct. Background Technology

[0002] Non-standard hot air circulating ovens are drying equipment customized according to customers' specific process requirements (such as size, temperature, and production capacity). Their core utilizes a forced hot air circulation system, which, through the design of the fan and air ducts, ensures that hot air flows evenly within the oven, penetrating the materials to achieve efficient and uniform drying. They are widely used in the chemical, food, and pharmaceutical industries.

[0003] In existing non-standard hot air circulating ovens, hot air is delivered to the material to be dried inside the oven through air ducts. However, the air outlets on the air ducts are located in fixed positions, which means that the hot air can only be delivered into the oven from one direction. The hot air has poor flow within the oven, resulting in the hot air not being able to contact the material evenly, and the oven's drying effect on the material is poor.

[0004] Therefore, those skilled in the art have proposed a non-standard hot air circulating oven duct to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned non-standard hot air circulating oven duct, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a non-standard hot air circulating oven duct, which is used to solve the problem of poor hot air flow in the duct leading to poor drying effect in the oven.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a non-standard hot air circulating oven air duct, comprising:

[0009] The oven body has a circulating air duct on its inner wall, and multiple air outlets are opened at both ends of the circulating air duct.

[0010] The adjustment assembly includes a rotating rod rotatably disposed on the inner wall of the air outlet, and an adjustment blade is connected to the rotating rod. The rear end of the rotating rod penetrates through the oven body and is used for conveying hot air in the circulating air duct.

[0029] Example 1

[0030] Reference Figure 1 and Figure 4 This is the first embodiment of the present invention, which provides a non-standard hot air circulating oven duct that can enhance hot air flow and thus improve the drying effect of the oven, including:

[0031] The oven body 100 has a circulating air duct 104 on its inner wall, and multiple air outlets 105 are opened at both ends of the circulating air duct 104.

[0032] It should be noted that the main body of the oven 100 is customized according to the customer's specific process requirements (such as size, temperature, and capacity), and is a non-standard oven. This is existing equipment. The air is delivered to the circulating air duct 104 by the operation of the fan, and the air is heated by the heater. The hot air is delivered to the oven through the air outlet 105 in the circulating air duct 104 to achieve the drying process of the materials. This is the working principle of the hot air circulating oven.

[0033] The adjustment assembly 200 includes a rotating rod 201 rotatably disposed on the inner wall of the air outlet 105, and an adjustment blade 202 is connected to the rotating rod 201. The rear end of the rotating rod 201 passes through the oven body 100 and is used for conveying hot air in the circulating air duct 104.

[0034] In use, the adjusting component 200 causes the rotating rod 201 to rotate, and the adjusting blade 202 fixed on the rotating rod 201 to rotate back and forth in the air outlet 105. This can transport the hot air in the circulating air duct 104 to the oven body 100, enhance the flow of hot air in the oven body 100, make the hot air contact the material evenly, and make the material dry more evenly, thus improving the drying effect of the non-standard hot air circulating oven.

[0035] Example 2

[0036] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the inner cavity of the oven body 100 is fixedly connected to a shelf 101 for placing the drying material. A blower 102 connected to the oven body 100 is also installed on the oven body 100. The shelf 101 is used to support the drying material, and the blower 102 delivers air into the oven body 100 when it operates.

[0037] The connection between the blower 102 and the circulating air duct 104 is provided with a mounting frame 103, and a filter 106 is provided inside the mounting frame 103. The mounting frame 103 extends through the front end of the oven body 100. The filter 106 has a multi-layer filtration structure to filter impurities in the air entering the oven body 100. The mounting frame 103 can be pulled out directly from the oven body 100, which facilitates the replacement of the filter 106 on the mounting frame 103.

[0038] The inner wall of the circulating air duct 104 is fixed with multiple sets of heaters 107, and multiple sets of circulating air holes are also opened on the circulating air duct 104; the heaters 107 heat the incoming air, and the multiple sets of air outlets 105 and circulating air holes transport the heat to the oven body 100 to realize the circulation of hot air.

[0039] The adjusting component 200 also includes a gear 203 fixed to the rotating rod 201. The rear end of the oven body 100 is provided with a reciprocating toothed plate 205 that moves back and forth, and the reciprocating toothed plate 205 is meshed with the gear 203.

[0040] The oven body 100 has a U-shaped frame 204 fixedly connected to its rear end. A vertical rod 206 is fixedly connected to the inner wall of the U-shaped frame 204. A sliding plate 207 is slidably connected to the vertical rod 206, and the sliding plate 207 is fixedly connected to the reciprocating toothed plate 205.

[0041] The outer wall of the vertical rod 206 is fitted with two sets of springs 208, which are located between the two ends of the slide plate 207 and the inner wall of the U-shaped frame 204. The two sets of springs 208 make the reciprocating toothed plate 205 fixed on the slide plate 207 elastic and enable the reciprocating toothed plate 205 to move up and down stably.

[0042] The oven body 100 has a fixed plate 209 fixedly connected to its rear end. A motor 210 is fixedly connected to the fixed plate 209, and the output end of the motor 210 is connected to a cam 211 via a rotating shaft for moving the slide plate 207. The operation of the motor 210 drives the cam 211 to rotate. The rotation of the cam 211 causes the elastically connected slide plate 207 and reciprocating toothed plate 205 to jump up and down. Since the reciprocating toothed plate 205 is meshed with multiple sets of gears 203, the rotating rod 201 fixed to the gears 203 can rotate, causing the adjusting blade 202 to rotate back and forth in the air outlet 105. This can transport the hot air in the circulating air duct 104 to the oven, enhancing the flow of hot air in the oven and making the material dry more evenly.

[0043] When in use, the cabinet door of the oven body 100 is opened, the dried material is placed on the shelf 101, and then the cabinet door is closed. The blower 102 operates, delivering air into the circulating air duct 104. The filter 106 filters the air, and the heater 107 heats the air in the circulating air duct 104. Multiple air outlets 105 deliver hot air into the oven body 100. During this process, the motor 210 of the adjusting component 200 operates, which drives the cam 211 to rotate. The rotation of the cam 211 causes the elastically connected sliding plate 207 and reciprocating toothed plate 205 to jump up and down. Since the reciprocating toothed plate 205 is meshed with multiple gears 203, the rotating rod 201 fixed to the gears 203 can rotate, causing the adjusting blade 202 to rotate back and forth in the air outlet 105. This can deliver the hot air in the circulating air duct 104 into the oven, enhancing the flow of hot air in the oven and making the material dry more evenly.

[0044] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0045] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
